The panel discuss the NightJack blog

Last week a serving officer who has been writing under the pseudonym Jack Night, won the Orwell Prize for political writing for his blog about the reality of policing in Britain.

A detective constable with 15 years experience, his blog NightJack - An English Detective offers an honest and compelling insight into the everyday life of the police and what he considers to be the failures of the criminal justice system.

This week's programme will be looking at the power of blogging and what NightJack can tell us about criminal justice.
